Hi. I am building a sauna. I have a 29th century cast iron column in the corner of the room that has to be left unclad. Could you recommend a non toxic paint for this application. Temperature of the sauna could be 100 degrees c.
Assuming the cast iron column is bare, clean, dry, sound and prepared as detailed in the technical data sheet you could consider the products below.
These are for professional use only.
Teamac High Performance 2 Pack Zinc Phosphate Primer followed by Teamac High Performance Polyurethane Topcoat.
This can be mixed to many RAL, NCS or BS colours in a gloss finish.
